In order to reduce the influence of the simulation result, the simplified models should be identical with the structure. Throat-insert of a SRM nozzle is one of the most important parts, which compresses gas in the process of motor working. It is very important to make strength analysis on throat-insert of a SRM nozzle. In this paper, a throat-insert of SRM was taken as an example. Three structure finite element throat models were created and calculated by the Abaqus software, and the three simplified methods are commonly used in the strength analysis of SRM. At last, the strength results were compared and discussed. The results show that different simplified models may have a significant impact on the results. Therefore, the specific situation should be analyzed according to the particular request in the finite element simulation, in order to ensure the accuracy of calculation results., correspAuthors=null,

articleAbstract=应用有限元仿真软件对结构进行强度分析时，要求仿真结果与结构实际情况相符合。在对结构进行建模时，要保证模型简化方式与结构实际情况一致，以减小模型简化对仿真结果造成的影响。喷管喉衬是固体火箭发动机中的重要零件之一，在发动机工作过程中起到压缩燃气的作用，因此对喉衬进行强度仿真十分重要。本文基于Abaqus仿真计算软件，以某固体火箭发动机的喷管喉衬为例，建立喉衬的3种有限元简化模型，分别进行有限元强度计算，并对仿真结果进行对比讨论。结果表明不同的简化模型可能会对仿真结果造成重大影响。因此，在采用有限元仿真分析时，应针对具体情况进行分析，以保证计算结果的精准度。,
